Patent DE-3528120-C1 (DE)
IPC: B23B31/16
Filed: 1985-08-06
Granted: 1986-09-25
Abstract: A power-operated chuck that is provided with a plurality of clamping jaws that are disposed in a chuck body in such a way as to be radially movable. The radial clamping movement of the clamping jaws is produced by a gear mechanism disposed in the chuck body and via an axial movement of a drive member. Radial positioning of the clamping jaws relative to the starting position of the drive member is adjustable, prior to carrying out a clamping stroke, for shifting the clamping stroke within the clamping range, with adjustment being effected by an adjustment member that acts simultaneously upon all of the clamping jaws. Via an additional axial movement, the drive member can be conveyed to a position that is beyond the clamping range, and in which position the clamping jaws are uncoupled from the drive member. An additional adjustment member is axially movably disposed in the chuck body. This member is connected via respective gear mechanisms to all of the clamping jaws, and during clamping movements of the drive member is carried along in a non-powered state. When the clamping jaws are uncoupled from the drive member, the adjustment member can be operated in a controlled manner to carry out a radial adjustment of the clamping jaws relative to the drive member.

Title: Four-wheel drive vehicle clutch - has two concentric clutch sections with sets of connecting pawls
IPC: F16D41/16
Filed: 1990-01-17
Granted: 1991-07-25
Abstract: The switchable freewheel clutch comprises two concentric freewheel parts and two sets of pawls which operate in opposed directions and are swivelled by associated control rings which can each rotate relative the first clutch part carrying the pawl sets. The two rings (6,7) are connected by a spring (21) counteracting relative rotation between the rings, and the rings can revolve within limits relative the first clutch part (2). Depending on the direction of rotation, an associated control transfers one pawl set into the torque transfer position whenever there is a difference in speed between the two parts of the clutch, and the control device uses a switch to lock the ring allocated to the pawl set not in torque transfer to the first part of the clutch. When stationary, this locking effect of the switch and control device is automatically cancelled and one of the pawl sets meshes with the toothing (8) on the second clutch part. USE/ADVANTAGE - Motor vehicles, four-wheel drive. Two-way freewheel clutch can transfer in both directions by pawl-switching ring and controls.

The columns are preferably anchored directly in the floor but, if required, can be placed on a foundation plate or in a foundation trough or on a prefabricated foundation. A prefabricated building can be simply enlarged during construction to meet the requirements of an incoming buyer in order to provide additional space. The one floor component (2b) can be provided with a casing-shaped structural component (5) equipped with central facilities, such as heating boiler, ventilation unit, electrical current provision and similar. All the floor components have a supporting layer in which the grooves are provided. Between the supporting layer and the top layer heated or cooled air, ventilation air, utility conduits and similar can be distributed.
